county of Kalamazoo, State of Michigan, have iuvented certain Improvements in Plow-Jointers, of which the following is a specification.

The tirst part ot' my invention relates to the providing ot' an ordinary share and mold-board, of suitable size for thepurpose, with cutting parts, in such a manner' as to cut clear a portion ofthe' inner angle or corner of thefurrow, and also cnt the soil below the part removed by the jointer-plow, the object of this part of my invention being to renderthe inversion or folding of the inner angle or part of the furrow upon the lnain portion more complete and with less draft, at the same time cutting thc earth or sod beneath the jointer.

'lhe second 'part of my invention relates to the combination of a peculiarly-formed cutter, with a curved standard, in such ,a manner as to entirely ob- ...j'iate the possibility of the', plow being clogged by straw, grass, or otllel obstructions.
